Abstract

Background/objectives: The Strengths and Difficulties Questionnaire (SDQ) is a widely used 25-item screening and diagnostic tool for behavioral and emotional problems in young people. Despite its popularity, evaluations of the SDQ's factor structure in adolescent populations have produced disparate results, and its relationships with theoretically related variables are rarely evaluated. In the present study, these two elements of validity were evaluated based on a large sample of Western Australian adolescents.

Methods: Participants were 1489 adolescents, n = 623 males with a mean age of 13.79 years (SD = 1.61) and n = 866 females, with a mean age of 14.29 years (SD = 1.51). Participants completed the SDQ alongside measures of loneliness, sense of belonging, depression, bullying, and diagnostic status to evaluate its internal structure and correlations with theoretically related variables.

Results: Confirmatory factor analyses supported the internal structure of the SDQ both for males and for females. Relationships between the SDQ subscale scores and those from theoretically related variables were also aligned with the instrument's underpinning framework.

Conclusions: Despite the somewhat disparate results of previous studies, overall, this study supported the validity of the SDQ for use in the Western Australian context.

用于西澳大利亚青少年筛查和诊断的优势与困难问卷的有效性。

背景/目的：优势与困难问卷（SDQ）是一种广泛使用的筛查和诊断青少年行为和情绪问题的工具，共有 25 个项目。尽管它很受欢迎，但在青少年群体中对 SDQ 的因子结构进行评估的结果却不尽相同，而且很少对它与理论相关变量之间的关系进行评估。在本研究中，我们根据西澳大利亚青少年的大量样本对这两个效度要素进行了评估：参与者为 1489 名青少年，其中男性 623 人，平均年龄 13.79 岁（SD = 1.61），女性 866 人，平均年龄 14.29 岁（SD = 1.51）。受试者在填写 SDQ 的同时，还填写了孤独感、归属感、抑郁、欺凌和诊断状态等测量指标，以评估其内部结构以及与理论相关变量的相关性：对男性和女性进行的确认性因子分析证实了 SDQ 的内部结构。SDQ子量表得分与理论相关变量得分之间的关系也符合该工具的基础框架：尽管之前的研究结果有些差异，但总体而言，本研究支持 SDQ 在西澳大利亚州环境中使用的有效性。
